HARROW.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed April 12, 1910. Serial No. 555,041.

.To all whom it may 'conccm:

Be it known that I, ROBERT D. lVHrrr, a citizen of the United States,residing at McNeil, in the county of Columbia and State of Arkansas,have invented a new and useful Harrow, of which the following is a specification.

This invention relates to improvements in harrows and one object of theinvention is to provide a simple and strong harrow which may be readilyattached to any ordinary plow foot or stock and which, when in use, willtravel smoothly and easily over the ground without any lateral twistingmovement. 7

A further object of the invention is to provide a harrow of thecharacter set forth which may be applied to the plow foot or stock in avery short time by an unskilled person and without the use ofcomplicated tools, and which will be strong and durable withoutexcessive weight.

These stated objects, and such other incidental objects as willhereinafter appear, are attained in the use of the device illustrated inthe accompanying drawings, and

the invention consists in certain novelifeatures of the same which willbe hereinafter first fully described and thcnmore particularly pointedout in the appended claims.

In the drawings, Figure 1 is aside elevation of a harrow embodying myinvention and showing the same applied to a plow foot. Fig. 2 is a planview of the same with the plow foot in section. Fig. 3 is'a detaillongitudinal section of the front end of the barrow.

The plow beam 1 may be of an desired construction and is equipped withiandles 2 and a foot or stock-3. In carrying out my present invention, Iemploy a substantially V-shaped frame lconsisting of a metallic barhaving a central curved portion 5 constituting the front end of thebarrow, and

side' arms diverging rearward from the said front portion. or polnt. Atintervals along the V-shaped bar, I form openings through which harrowteeth 6 are insertedand in which the said teeth are. secured by means ofnuts 7 mounted on the said teeth and turned home against the upper andlower sides of to the point or front portion 5 of the frame and extendslongitudinally rearward therefrom and has its rear end bent upward, as

shown at 9, to provide a. lip adapted to bearagainst the front side ofthe plow stockor foot and be secured thereto by the bolt 10 whichordinarily secures the plow shovel. To the rear ends of the frame Isecure the ends of a V-shaped brace 11 which converges forward from thesaid ends and has its ceninverted position, as indicated by dotted linesin Fig. 1, whereby the loss of the teeth will be prevented, and theywill be at hand should it be desired to again bring them into anoperative position. The several parts are secured to the plow foot bythe bolt 10 inserted through registering openings'in the brace 11 andthe lip 9 and extending through the end of the plow foot and carrying anut 12- which is turned home against the rear side of the plow foot soas to clamp the parts firmly together,- as will be readily understood onreference to Fig. 3.

From the foregoing description, taken in connection with theaccompz-inying drawings, it will be seenithat I have provided anexceedingly simple and durable harro w which may be readily attached toany ordinary plow foot or stock and which, when in use, will moveoverthe ground easily and without any lateral movement, inasmuch as boththe rear ends and the front point of the burrow frame are connectedwitlrthe plow 7 foot by rigid braces and connecting plates, so that thedevice will be held positively and firmly in its proper relation withthe plow foot. In order to attach my barrow tothe plow foot, it isnecessary merely/to remove the plow shovel and then insert the boltwhich held the shovel through the register ing openings in the brace 11,the plate 8 and the end of the plow foot, and secure the same. Thedevice; is light in weightand possesses great durability, inasmuch asthe parts are all of metal and are not of a com plicated arrangement andconstruction and may be drawn over any field without excessive strain onthe draft animals, and as the frame is connected with the plow stockfrom both its rear ends as well as from its the ground and will loosenthe soil thonoughly around all the plants without dis ging up any of thesame or without uncov ering any seeds which have not sprouted. Should itbe desired to have the harrow moved over a. row of plants, the teethwhich would naturally ride directly upon the plants may be inverted inthe manner hereinbefore described, so that injury to the plants will notoccur.

The advantages of the construction and of the method of operation willbe readily apparent to those skilled in the art to which the inventionappertains, and while I have described the principle of operation of theinvention, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative, and that such changes may be made when desiredas are within the scope of the claims appended hereto. 7

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

.l. The combination of a V-shaped harrow frame, a V-shaped brace havingits ends socured to the said frame and its apex provided with means forsecuring the same to a plow stock, and a rigid connection between theapex of the frame and the said plow stock. I

2. In a harrow, the combination of a V- shaped frame, and a V-shapedbrace secured to the rear ends of the saidframe and havin; its'centralportion adapted to be secured to a plow stock.

3. In a barrow, the combination of a V- 51 m frame, a connecting platesecured to the front point of the said frame and. exlendine rearwardlytherefrom and having its rear end formed into a lip adapted to bearagainst the front side of a plow stock,

and a V-shaped brace secured to the rear ends of the frame and havingits central portion extending across and lying againstlhe said lipwhereby the said brace and lip may be secured to a plow stock.

4-. In a barrow, the combination of a V- shaped frame, a V-shaped bracesecured to the rear ends of the said frame and having its centralportion adapted to be secured to a plow stock, and a connection betweenthe apex of the brace and the apex of the frame.

5. The combination of the harrow frame, a Vshaped'brace having its endssecured to the said frame and its apex provided with means for securingthe same to a plow stock, the apex of the brace being. spaced from thefront end of the frame, and a rigid connection between the said frameand the apex of the said brace, said connection being attached also tothe plow stock.

In testimony, that I claim the foregoing as my own, I have heretoaflixed my signae ture in the presence of two witnesses,
